|---|---|---|---|---|
Purposedifferent | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. | When users immediately turn the wrong way on a screen or wireframe, first click testing checks initial orientation at high speed. The first click shows early whether expectation, labeling, and wayfinding fit together. | When content only makes sense internally and users can't find the structure again, card sorting exposes their mental order. Terms, groups, and naming are then aligned with the target group's expectations. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. |
Complexitydifferent | Medium | Low | Low | High |
Timedifferent | 45-120 min | 1-2 Tage | 20-45 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 2-6 | 10-30 | Based on research question | Architecture experts and stakeholders for scenarios and weighting |
Formatdifferent | Workshop + async | Async | Workshop + async | Workshop + async |
Outputdifferent | Change Matrix, Cause Hypotheses, Validation Questions, Action List | Click Heatmap, Success Rate, Design Recommendations | Content groups, Label set, IA hypotheses | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives |
